Hi I'm encountering an error with some of my Windows clients when using CTDB and samba to access a GPFS hosted share. We see the following error all the time. [2011/03/14 12:31:16.549084, 1] modules/vfs_gpfs.c:1099(vfs_gpfs_ntimes) vfs_gpfs_ntimes: set GPFS ntimes failed -1 The copy continues but is slow. All the timestamps seem reasonable for the data copied. The GPFS

Hi We have a ctdb cluster setup as follows ctdb version -- surprisingly difficult to determine. I think it is 1.0.99 (dragged from a include file somewhere, I forget where exactly ). If anyone can tell me how to determine this proberly then I would be pleased to know. samba version 3.5.8 I was hoping to be able to set the UID to SID mapping manually using the following procedure.

Hi Is there a way of getting samba to use the passwd file entries when utilising POSIX extended acls. I have two groups of users 1) A vast amount of users who access filestore via windows only. In this case I winbind and idmap to assign random UNIX uids as is normal. 2) I also have a much smaller group of users who use NFS and CIFS to access the same area. In this case I put an entry in

Hi, I am setting up ctdb samba, and have hit a brick wall trying to solve the following issue. 1. getent does not retrieve the list of domain users or groups (wbinfo works fine) I'm not sure what I'm missing but I've almost spent the whole day trying to resolve this one and haven't made any progress :-( Any help or suggestions are appreciated My configuration is

Hi all, We're running gpfs 3.5.0.12 (5 total nsds & quorum servers, 2 nsds running samba), sernet-samba 4.1.4-7, and ctdb 1.0.114.7-1 and trying to get transparent failover to work from a windows 8 client. We have ctdb failover working, i.e. if I run mmshutdown on one of the nodes the IPs failover in a few seconds after the GPFS mount is unmounted. For our transparent failover test, I

Dear list, We are about to upgrade to Samba 4.2.9 from sernet-samba 4.1.6 + CTDB 1.0.114.7 running on top of GPFS. My understanding is that as of 4.2, CTDB is now part of Samba. So does this mean we need to uninstall all of our sernet-samba and ctdb RPMs (we are on CentOS 6), then install the sernet-samba 4.2.9 rpms and reconfigure everything for CTDB? For those who have done this, how

Hi, in the following scenario I've got the Problem of "STATUS_SHARE_VIOLATION". Client A (with User 1) copies a file to share X. (with: DENY_NONE 0x120196 WRONLY NONE) Client B (with User 1) reads this file from share X (with: DENY_NONE 0x120089 RDONLY NONE) Now Client C (with User 1) wants also to read this file from share X and gets the STATUS_SHARE_VIOLATION.

Hi All, Are there any special CTDB/SMB configuration settings/dependencies to manage Winbind across CTDB managed servers authenticating via Active Directory(AD)? An example would be Samba's IDMAP backend for Winbind: RID vs. AD or tag Winbind to a primary CTDB node and point other nodes to authenticate from AD via proxy primary CTDB node? /etc/sysconfig/ctdb on all nodes is as follows:

I have been working on a CTDB cluster on and off for a while now. I had it working great for a while. THen I decide dthat I wanted to change the configuration of my replicated volumes. I changed my DRBD configuration to match my desired configuration. Now I can get the CTDB to work quite right. I am able to join the cluster to the domain without issues. I can also list my ad users and groups using

Hi everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies 2 active-active nodes. Does CTDB care if the node starts with clean_start="0" or

Hi , I have set up a 2-node CTDB cluster serving NFS and CIFS authenticating Windows and Linux users via Active Directory. The setup works fine, except only one server in the CTDB-cluster is able to join the AD domain at a given instance. If you manually add the other server into AD, the already connected server gets disconnected. There is no specific error message logged in /var/log/message or

Hi Samba, I hope you are doing well. I run a cifs / nfs CTDB clustered NAS solution, and I find that when I reboot any of the nodes in the cluster, I must re-export the nfs mounts so they show up properly. Perhaps this is a general linux nfs bug and I am barking up the wrong tree, but I haven't found any problem / solution mentioning this as of yet besides my own known workaround

Hi All, My site has two separate clustered Samba instances (managed by two independent CTDB instances) running over GPFS. In the last couple of weeks, we have seen a recurring issue that causes the `smbd` process in *one* of these instances to become unresponsive (as seen by CTDB), which results in flapping of CTDB and multiple IP takeover runs. The symptoms that we observe are: 1) Samba

I have been running ctdb on our cluster for ~6 months to serve a gpfs filesystem over nfs. It has been running a treat :) ! Recently the servers were upgraded to redhat 5.7 and ctdb-1.0.112-1.el5 is part of the package list. Since the upgrade the log file is filled with messages 2011/10/04 12:35:37.933801 [ 1779]: basename: missing operand 2011/10/04 12:35:37.933850 [ 1779]: Try `basename

Hi everyone, I'm sorry if this has already been covered somewhere, but I've had a look and can't find it. Also if there is a better place for this question, please let me know. I know that the CTDB documentation states that only NFS2/3 are supported with CTDB but what I'd really like to know is why NFS4 won't work and if NFS4 support is planned for the future (timeline?).

Hi, last weekend I've updated samba and ctdb on my 2-node cluster. Samba is now on 3.5.6 (from 3.3.4), ctdb on 1.0.114 (from 1.0.84). Both installed from repo via yum and ctdb-packages. After restarting both nodes everything was fine, we could access files on the cluster. On monday I noticed that the nodes didn't had their initial adresses: Node 1: hostname dscln01, public IP

Hello, I'm using the Samba server 3.0.33 that exports volume from a GPFS. The GPFS strongly dislikes unlinking files that are locked (resulting in permission denied) using fcntl F_SETLEASE. It seems that the Samba *sometimes* tries to unlink a file that is oplocked. Why? Is this a bug? Why it does not happen always but only sometimes? I have strace logs showing: Wrong case: 8711

Greetings, Does anyone know whether I'll encounter problems serving out CIFS using Samba/CTDB where the servers are pNFS clients? Specifically I'm thinking that I'll have a number of RHEL 6.2 boxes connecting to netapp storage using pNFS. These boxes will then serve a variety of CIFS clients. JR

Hi everyone I have a four node samba/CTDB cluster exporting CIFS shares from a GPFS 3.5 cluster.

Hi Rob, on your Info for Version 3.0.25 you pointed out the VFS-Module GPFS for using features of the underlaying GPFS-Filesystem. Also the man-pages-3/vfs_gpfs.8.html points to that module, but I can't find it anywhere. We are using a GPFS 3.2 3-Node Samba Cluster (3.0.24/28) on Dell HW. We would be very glad if it is posible to get - Quota Recognition for our users (we use "max
